## What is simple pendulum experiment?

Cut a piece of a string or dental floss so that it is about 1 m long. Attach a small object of high density to the end of the string (for example, a metal nut or a car key). Starting at an angle of less than 10º, allow the pendulum to swing and measure the pendulum’s period for 10 oscillations using a stopwatch.

## Who introduced simple pendulum?

Christiaan Huygens
The Italian scientist Galileo first noted (c. 1583) the constancy of a pendulum’s period by comparing the movement of a swinging lamp in a Pisa cathedral with his pulse rate. The Dutch mathematician and scientist Christiaan Huygens invented a clock controlled by the motion of a pendulum in 1656.

How do you draw a simple pendulum graph?

Plot a graph between l (column, 2b) and T2 (column 5) by taking Z along X- axis and T2 along Y-axis. The graph comes to be a straight line. From this graph, for T2 = 4, l comes to be 100 cm. Hence for seconds pendulum (T = 2 s) length comes to be 100 cm.

### How can we make a simple pendulum for Class 7?

A simple pendulum can be made by tying about one metre long thread to a small metal ball (called bob) and suspending it from a rigid support so that the bob is free to swing When the pendulum is at rest, then its bob is at the mean position.

### Why do we use simple pendulum?

Pendulums are used to regulate the movement of clocks because the interval of time for each complete oscillation, called the period, is constant. A simple pendulum consists of a bob suspended at the end of a thread that is so light as to be considered massless.

Is gravity an acceleration?

Gravity is measured by the acceleration that it gives to freely falling objects. At Earth’s surface the acceleration of gravity is about 9.8 metres (32 feet) per second per second. Thus, for every second an object is in free fall, its speed increases by about 9.8 metres per second.

#### What is pendulum energy?

An ideal pendulum system always contains a stable amount of mechanical energy, that is, the total of kinetic plus potential energy. As the pendulum swings back and forth, the balance between the two types of energy changes constantly. At some points in its swing, the pendulum has more kinetic energy.

#### What is the formula for simple pendulum?

Attach the C-clamp to the ring stand so that it is perpendicular to the stand.

• Cut a string that is 0.2m long,or just long enough so that there is an inch between the ground and the string when it is tied.
• Next,tie a washer to the bottom of the string.
• Measure the distance between the top of the string and the bottom of the washer.
• How to solve the pendulum?

The potential energy is simply the sum of the cosine components of both lengths.

• The x {\\displaystyle x} and y {\\displaystyle y} positions of the second bob are found as follows.
• Now we differentiate with respect to time.
• Since K = 1 2 m v 2 = 1 2 m ( x ˙ 2+y ˙ 2),{\\displaystyle K= {\\frac {1} {2}}mv^{2}= {\\frac {1} {2}}m\\left (
• ## What is a simple pendulum?

The simple pendulum is a mechanical system that sways or moves in an oscillatory motion. This motion occurs in a vertical plane and is mainly driven by the gravitational force. Interestingly, the bob that is suspended at the end of a thread very light somewhat we can say it is even massless.

## What is the pendulum experiment?

EXPERIMENT: THE PENDULUM OBJECTIVES • to investigate the functional dependence of the period (T) of a pendulum on its length (L), the mass of its bob (m), and the starting angle (θo) • to check for systematic errors by calculating g APPARATUS Point masses and string, a digital timer, period gate, and meter stick will be used.
